I think an intelligent girl would prefer not to be fed some PUA lines, but that may just be a bias I have against the whole idea.
Be intelligent, honest and compassionate. Use your wit. If you are living in such a way that you take responsibility for your life and live it joyfully, you will attract people to you like nothing else.
BTW, I don't like diamonds unless they are certified conflict free and even then there are so many things I would prefer a man give me...like integrity.
